It sits just west of centre within a rath, the kind of circular earthen enclosure that served as a defended farmstead throughout early medieval Ireland, typically enclosing a house and outbuildings for a single family or small community. What makes this particular trace quietly compelling is how little is known about it. No date has been firmly established, and the structure exists now as little more than a footprint pressed into the interior of an enclosure that already predates easy explanation.

The site at Ballybrit was recorded by the archaeologist John Waddell in 1971, with the house traces noted in his published findings from that year. The rectangular form is visible within the rath, which carries its own separate monument reference, suggesting both features have been individually assessed and recognised as significant. The building's proportions are modest but coherent, roughly the scale of a substantial single room or small hall, and its positioning within the enclosure follows a pattern seen at comparable sites elsewhere in Ireland, where domestic structures cluster toward one side of the interior rather than occupying the geometric centre.
